这份来自JetBrains Support的官方文档认为应该包含以下内容:

All files under .idea directory except workspace.xml and tasks.xml because
    they store specific user settings
All the *.iml files that can be located in different module directories

它还给出了其他需要注意的事项的建议。

我有忽略构建文件的问题，但这似乎是有效的:-)

使用Android Studio 3.0测试

你可能需要安装.ignore插件。

你可以为Android自动生成.gitignore文件。 右键单击文件夹并跟随

然后从左侧面板选择Android，单击Generate

Android Studio将生成.gitignore文件，其中包含所有需要忽略的文件。

使用gitignore提供的api。Io，你可以得到的是自动生成的。这里是gitignore.io/api/androidstudio的直接链接

我支持提交。idea文件夹(不包括workspace.xml和tasks.xml)。但我开始得出结论，.iml文件应该被忽略。

问题在于:

例如，在名为“foo”的目录下打开一个项目，你将得到foo。我和那一切看起来都很好。问题是，如果我只是将目录重命名为foo2(或克隆为另一个目录名)，当你尝试在Android Studio中打开项目时，你会得到三件事:

一个名为foo2.iml的新iml文件 你的Android项目的iml文件将被更改为指向foo2作为它的父文件 .idea/modules.xml将为foo2添加一行。它既有旧的Iml文件，也有新目录的Iml文件

我找不到方法来阻止Android工作室做这个iml文件生成时，项目存储在一个不同的目录。将它们添加到源代码控制中会导致问题。因此，我认为也许我们应该忽略*。Iml文件和。idea/modules.xml
